This page from Suzanne Alejandre's Math Forum blog has links to nine short videos (5 minutes or less) of Ms. Alejandre implementing the "Wooden Legs" Problem of the Week with a fifth grade class. The "Notice/Wonder" strategy is used to introduce the problem, and additional materials describe other problem solving strategies. The blogpost describes the goals of the lesson and also includes links to the teacher materials including the problem, solution, sample student answers, a scoring rubric, and teaching suggestions. Suggested browsers are Chrome, Firefox, or Safari. (It's been reported to us that when using IE9 (PC) the videos do not display.)
